Magnesia Bricks

Magnesite spinel bricks are refractory bricks made from a combination of magnesite (MgO) and spinel (MgAl2O4) minerals. These bricks are used in high-temperature applications where excellent thermal and chemical resistance is required, such as in the lining of steelmaking furnaces, cement kilns, and other industrial furnaces.

Magnesia chromite bricks are a type of refractory brick that is commonly used in high-temperature applications, such as in steel, non-ferrous metal, and glass industries. These bricks are known for their excellent resistance to corrosion and high thermal stability. 

Refractory magnesia brick, often referred to as magnesite brick or magnesia refractory brick, is a type of refractory material made primarily from magnesia (magnesium oxide, MgO) as the main component. Magnesia bricks are known for their high refractoriness and excellent resistance to high temperatures.

Low-creep clay bricks are now one of the commonly used refractory bricks in blast furnaces and hot blast furnaces, and as the wind temperature increases, the creep resistance of clay bricks increases. Low creep clay bricks are made of coke clinker with dense structure and high initial. And a few impurities as the main raw material, adding part of synthetic mullite and trilithon raw materials to configure into clay, which will be formed under high pressure, dried and fired at high temperature.

Magnesia-alumina spinel brick refers to a synthetic spinel refractory raw material using magnesium oxide and aluminum trioxide as raw materials. This raw material is rarely found in nature, and magnesium-aluminum spinel used in industry is all artificially synthesized. Bauxite-based sintered magnesia-aluminum spinel uses high-quality alumina with an Al2O3 content of more than 76% and high-quality light-burned magnesium powder with an MgO content of more than 95%. After a multi-stage homogenization process, it is heated to 1800°C in an ultra-high temperature tunnel kiln. It is sintered at the above high temperature.

Magnesia carbon bricks are made of high melting point alkaline oxide magnesium oxide (melting point 2800°C) and high melting point carbon materials that are difficult to be wetted by slag as raw materials, and various non-oxide additives are added. Non-burning carbon composite refractory material combined with carbon binder. Magnesia carbon bricks are mainly used for the lining of converters, AC electric arc furnaces, DC electric arc furnaces, and the slag lines of ladles. As a composite refractory material, magnesia-carbon bricks effectively utilize the strong resistance to slag erosion of magnesia and the high thermal conductivity and low expansion of carbon, compensating for the biggest shortcoming of magnesia's poor spalling resistance.

Magnesia-chrome bricks are refractory products with magnesium oxide (MgO) and chromium trioxide (Cr2O3) as the main components, and periclase and spinel as the main mineral components. This type of brick has high refractory resistance, high high-temperature strength, strong resistance to alkaline slag erosion, excellent thermal stability, and certain adaptability to acidic slag. The main raw materials for manufacturing magnesia chrome bricks are sintered magnesia and chromite

Magnesia iron spinel brick is a new generation of alkaline refractory with more technical content. It is mainly used in the firing zone of large dry process cement kiln. The microstructural characteristics of magnesia-aluminum spinel are relatively complex, mainly a combination of magnesia microstructure and iron-aluminum spinel microstructure. The interface between magnesia and iron-aluminum spinel is formed by Mg2+, Al3+, Fe2+ ions. The mutual diffusion and close combination realize the direct combination of materials.
